SCREW-STOPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 380,782, dated April10, 1888.

Application filed December 21, 1887.

To all whom it may concern:

Be it known that we, HENRY BARRETT and JOHN JAMES VARLEY, subjects ofthe Queen of Great Britain, residing at London,England, have inventednew and useful Improvements in or applicable to Screw-Stoppers forBottles Containing Aerated or Gaseous Liquids, of which the following isa specification.

This invention relates to an improved con struction of valvescrew-stopper, whereby bottles closed with such stoppers can be filledor charged with aerated or gaseousliquid in a better or more convenientmanner than hitherto.

Until now in almost all screw-stoppers having valves through whichbottles can be filled after the stopper is placed in the neck the valveshave had to depend upon springs (for the most part metal springs) orupon the internal pressure ofgas within the bottle for hold ing orkeeping the valve up to its seat.

According to our invention we make use of the elastic property of thematerial from which the valve is made-videlicet, india rubber forclosing the valve by constructing the stopper and valve in the mannerhereinafter more particularly described, and shown in the accompanyingdrawings, in which- Figures 1, 2, and 3 are respectively an elevationand vertical sections of one of my improved stoppers; Figs. 4, 5, 6,similar views of the same, except that a slotted opening, is made in thebottom of the stopper and extend ing up to the hole d,- Figs. 7, 8, 9,similar views in which the rubber valve is a ball instead of a plug;Figs. 10 and 11, an elevation and ver tical section, in which the lowerend of the stopper is cut away. Figs. 12 and 13 show the valve-hole inthe main body of thestopper,and Fig. 14. is a section showing the mannerof opening the passages by compressing the valve by a rod.

The invention may be carried out in several ways, some of which areillustrated in the accompanying sheet of drawings. In one modification(represented in side elevation and vertical sections at Figs. 1, 2, and3, respectively,) we take a screw-stopper, a, of the kind now used withbottles having a quick coarse female screw-thread in the neck, intowhich the stopper fits, ajoint being made in the cone at the mouth ofthe bottle by the elastic ring I).

The

Serial No. 258.597. (No model.)

stopper is made of any suitable material; but we form it with a hole, 0,running down the center and out at the point or lower end of thestopper. A hole or passage, (1, is also made running at right angleswith the central hole, 0, and in this transverse hole d we place ourindia-rubber valve 6, which may be formed of a short length of cord ofcircular or other shape in cross-section, according to the shape of thetransverse hole or passage 12. The diameter of the cord should besomewhat greater than that of the passage d, so that the rubber cordwill have to becompressed to place it in the passage. When this cord isin its place, it will close up the end of the central hole, a, runningthrough the stopper, and the-elastic nature of the india rubber cordwill keep it pressed tightly against the end of the said central hole,which forms its seat, and so make a tight joint.

A hole or holes, f, is or are made in the end of the stopper at the sidethereof, the said hole or holes passing to the hole (I, in which thevalve e is placed, and which hole or holes f is or are uncovered toallow the liquid to pass into the bottle when the valve is pressedinward either by the pressure of the liquid or otherwise-as, forinstance, by a pressing-rod.

The stopper shown in elevation and vertical sections at Figs. 4, 5, and6, respectively, is the same as that shown at Figs. 1, 2, and 3, withthe exception that a slotted opening, 9, is made in the bottom of thestopper to the hole (I.

In place of the above-named valve 6, we sometimes cmploy a rubber ball,e, to form the valve, as shown in the stopper represented in elevationand verticalscctions at Figs. 7, 8, and 9, respectively.

Figs. 10 and 11 represent an elevation and a vertical section of astopper similar to that shown in Figs. 1, 2, and 3, except that thelower end of the stopper is cut away at each side, as sh own at hh,whereby, the valve e having less bearing-surface, the holes f are notrequired.

In Figs. 12 and 13 we show an elevation and section of a stopper, inwhich the valve 6 is placed in a hole, d, made through the middle partof the stopper. In this case, as the rubber valve does not extend fromone end of the hole (I to the other, the holes f f are not required.

In order to fill a bottle closed with one of ourimproved stoppers, thestopper is screwed tightly into the neck of the bottle and the bottlefilled by a suitable filling-machine through the central hole, 0, thepressure being sufficient to press down the valve e, so as to allow theliquid to pass through small holes-such as f into the bottle. WVhen thebottle has been sufficiently filled, a pressing rod or needlesuch as iisemployed to press down the india-rubber forming the valve 0, as shown inFig. 14, and the excess of air or gas is allowed to escape, or, as it istechanically termed, snifted through the holesff, and upon the presseror needlei being removed the valve 6 will close the openings 0 andf. Inthe case of the stopper shown in Figs. 10, 11, 12, and 13 the bottle isfilled and snifted through the hole d.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat What we claim is 1. A screw-stopper having within intersectingpassages made through its body a stationary valve of elastic materialand of larger di- 25 ameter than its valve-seat, and serving by its ownresilience to close at the same time both said passages.

2. Ascrew'stopper forbottles havingtherein an axial'and a transversebore communicating 0 with each other, and an elastic valve serving byits own elasticity to close such communication.

3. A screw-stopper with a vertical passage,

0, having a gradual downward taper, a transverse passage intersectingthe same near its 5 bottom, and a tight-fitting elastic valve lodged inthe space where these passages intersect.
